Hungarian Constitution: a demagogic attack against Hungarian sovereignty by the European Socialists 2011. 04. 19. Press Release of the Hungarian EPP Group Delegation - By calling on the European Commission to assess the recently-adopted new Hungarian Constitution by the S&D Group, in a press release issued today, is a serious attack against Hungarian sovereignty. Constitutionalism is part of national sovereignty and even Mr Schulz and the European Socialists should not question the right of the Hungarian Parliament, whose members were elected by Hungarian citizens in a democratic way, to adopt a new constitution. Mr Schulz should have rather called his Hungarian Socialist fellows to represent their voters and participate in the debate in the Hungarian Parliament on the new Constitution, which they refused to do.
